Gulf Breeze, Fla. — Just a month ago, Braylynn Lawhon of Gulf Breeze, Florida, was a seemingly healthy little girl, excitedly preparing to celebrate her 5th birthday. Doctors now say she could die at any moment.

The girl was diagnosed with Diffuse Intrinsic Pontine Glioma, a deadly form of brain cancer.

Braylynn’s mother, Ally Parker, has been posting updates on her daughter’s condition on Facebook.

She recently shared an image that captures the brutality of cancer: Braylynn’s grandfather, 49-year-old Sean Peterson, who suffers ALS*, overwhelmed by sadness as he visited his sick granddaughter.

“They wheeled him in to see Braylynn. He can no longer speak, he can’t move his hands and he has a feeding tube,” Beth Peterson-Hickman, Braylynn’s grandmother and Peterson’s ex-wife, told PEOPLE. “When he saw her, he was crying and it was heart-wrenching. I broke down and I had to turn around.”

The image has gone viral and has been shared nearly 5,000 times.

A GoFundMe** account has been created for Braylynn’s medical expenses. Ally Parker shares updates on Braylynn’s condition on Braylynn’s Battalion Facebook page.

*This story has been corrected. Originally it said Mr. Peterson suffered bone marrow cancer and ALS. He doesn't not have bone marrow cancer per his daughter.
